FAQs: I-BEAM LED
®
Where would I use the I-BEAM LED (IBL) high bay?
The I-BEAM LED luminaire was designed to match the lumen
output and footcandle levels produced by fluorescent high bays.
Ideal for warehouses, manufacturing, gymnasiums, convention
centers, aircraft hangers and other large indoor spaces with
mounting heights up to 60 feet. With six lumen packages and two
optical distributions to choose from, the I-BEAM LED fixture has a
configuration to fit your application.
What makes the I-BEAM LED a better value than other
LED high bays?
The base unit uses the same electronics and quality controls as a
fully optioned model. The fixture ships with a premium reflector,
high efficiency drivers and 0-10V dimming – all in a rigid and
attractive solution with an average weight of 15 pounds (9L-24L)
or 35 pounds (36L-48L).*

What advantage does the I-BEAM LED fixture have over
traditional lighting?
Input wattage is significantly reduced compared to traditional
sources. Provides payback in as little as two years and a high
return on investment over the life cycle when compared to
traditional sources.
What is the predicted life and maintenance schedule?
With 95% lumen maintenance (L95) at 60,000 hours and a
predicted useful life beyond 100,000 hours, maintenance costs
are minimal. Traditional sources require regular maintenance and
lamp recycling. When you consider the costs associated with
maintenance, the I-BEAM LED luminaire will save you hundreds of
dollars over the useful life of the product.

Can I save additional energy with optional controls?
How does I-BEAM LED control glare?
Yes, and it is a great way to maximize your return on
investment. The I-BEAM LED fixture can be equipped with an
occupancy sensor, photocell, nLight® and XPoint™ Wireless
technology. These devices are factory-installed and require
minimal labor to set up during fixture installation.
A semi-diffuse acrylic diffuser is available to cover the emitters
and reflectors. It can be factory- or field-installed.
Can the I-BEAM LED high bay be nLight® or enabled for
individual fixture control?
Yes. nLight® is a revolutionary system that cost-effectively
combines time-based and sensor-based lighting controls.
The digital interface allows for quick and easy modifications to the
time delays, photocell sensitivity and light levels at the individual
fixture level.
What options and accessories are available?
I-BEAM LED is available with the vast majority of I-BEAM IBZ
(fluorescent) offerings. Some items, such as shielding and wire
guards are different in shape, but equivalent in performance.
Other accessories such as hangers, cords and sensors are
identical and interchangeable with I-BEAM IBZ.
Does the I-BEAM LED high bay come in different colors?
The standard fixture is two-toned with a white body and textured
dark gray channel and end caps. An all-white version is optional.
Can I dim the I-BEAM LED high bay?
Yes. The drivers come standard with 0-10V dimming leads. They
are capable of variable dimming down to 10%.
What parts are field replaceable?
LED boards, drivers, fusing, lensing and wire guards are all field
replaceable.
Is there an emergency battery pack option?
Yes this option is available in fixtures up to 24,000 lumens only.
We can factory-install an emergency battery pack in the center
channel; cannot be installed in the field. This option provides 1000
lumens (nominal) for a minimum of 90 minutes.
Will the I-BEAM LED fixture provide the same light output
regardless of the ambient temperature in which it is
installed?
No. Much like fluorescent lighting, LED output varies with
temperature. It offers higher light levels at colder temperatures.
In hot environments, the relative light output decreases at about
the same rate as fluorescent high bay sources. See spec sheet for
details.
As with most LED solutions, the upfront cost is higher
than traditional sources. What is being done to ensure
product reliability?
Prior to production, each configuration is tested to UL standards,
and further subjected to testing that identifies the electrical and
thermal limits of the product. During assembly, components are
selected and assembled according to IPC-A-610 standards and
each fixture is thoroughly tested prior to shipment.
What is the standard warranty?
There is a 5-year limited warranty. Complete warranty terms are
located at www.acuitybrands.com/CustomerResources/Terms_
and_conditions.aspx
What is the standard color rendering index (CRI)?
The standard LEDs are 70 CRI to meet DesignLights Consortium
(DLC) requirements. 80 CRI is available as an option in all models;
lumen output is decreased by 10%.
DesignLights Consortium® (DLC) qualified product.
